    Kingslayer Quality

    This is the first SwampFox optic that I have ordered and I will say that I am very pleased with the company and the product. This sight is perfect for my application, the first thing that stood out was just how bright the reticle can be, no problem on the brightest of days. The glass is very clear and the sight feels very solid. The fit and finish of the sight is very well done and as of this review no complaints. I will be ordering another one for sure.

    Couldn’t be more pleased

    Posted by Marcus Christian on May 27th 2020

    Although I haven’t had a chance to take it to the range, I’m happy with my purchase and have become as proficient with it as can be with dry fire practice. The optic is clear and easily picked up when drawing. Mine actually came with two batteries which is great since I’ve heard people complain about battery life. This should keep me going for at least 2 years. I have zero complaints with the Kingslayer. I believe it will be around for awhile.

    Great Optic!

    This optic is awesome. Very easy installation and brilliant esthetics goes brilliantly with my Sons of Liberty Gun Works setup. Glass is super clear and the footprint is a perfect match with my Arisaka mount.

    KING SLAYER Red Circle Dot

    I am impressed with this optic. I have it on my KSG with a riser mount and it is spot on. The sight is clear and has no bleed in the sight. So far it is flawless. I am glad I made this purchase and will make future purchases if I need a quality sight.

    King slayer

    Posted by Donald on May 16th 2020

    I received the king slayer in three days after ordering. It’s a very high quality optic. It’s well made from lightweight aluminum and the glass is super clear. It compares to much more expensive optics I have. The green 65moa dot is crisp with no bleeding. Wide range of brightness. The packaging and extras that came in the box drips of high quality. Swampfox is going to be my go to optic company. You won’t be disappointed in this optic. I highly recommend it.

    This optic is awesome! Purchased it last fall and I am in love! I installed it on a Ruger 10/22 that I have built for USPSA Steel Challenge competition and it is awesome! I will be replacing my older FastFires on other firearms in the near future! Thanks for making a top quality product at an amazing price point!

    King slayer green circle dot

    Fantastic sight sitting on my mossberg shotgun. Crisp sight and looks great. Held up good so far. Only complaint is the super low battery life.

    Pretty much everything you need comes in the box. The housing is great. Free from any tooling or manufacturer defects. Finish is perfect. My green reticle is crisp and daylight bright. Buttons have a nice tactile feel. When moving up or down in brightness, there is no flicker of reticle. Mounted currently on Remington 870 Tactical. Handles slugs and 00 like a boss. I love this optic. At this price and quality, you just can't go wrong. Buy one, you won't regret it!
